'1 0 all whom it may concern:

Be it known that I, Nnrr E. IAnrsn, a citizen of the United States, and a resident of Cleveland, county of G1 yahoga, and State of Ohio, have invented a new and useful Improvement in Car-lines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distingnish it from other'inventions.

My invention relates to carlines for supporting the roof-purlins of box cars, and its object is to provide a ear-line having the least possible depth, at the same time liaving the necessary resistance to flexure and also being economical in its construction.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying the invention, said disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed lrawing:Figurc lv represents a side elevation of a part of a carline embodying my invention. Fig. 2 represents a plan of the same. Fig. 3 represents an end elevation of the said car-line. Fig. 4 represents, on an enlarged scale, a perspective view of one end of a modified form of said carline, and Fig. Srepresents a similar view of one end of a second modified form thereof. Fig. 6 represents a side elevation of one end of one form of th e carline, together with a vertical section of one of the side plates of the car, this view illustrating the relative location of such carline and side plate. Fig. 7 represents a cross section ofone form of the carline taken upon the plane indicated by line 7-7, 1.

My improved carline A is struck .up, cold-pressed, by

means of suitabledies and punches,'from single piece of sheet steel of uniform thickness, to form a cross section of inverted (T-shape. In the top or closed portion of the-carline are formed a number of depressions or re cesses a for receiving the roof-purlins, and the side members a a are vertical, parallel with each other and their outer lateral surfaces 11 a Figs-2 and 7, lie in the desirable. By mcans of such construction the carline may be designed in accordance with the laws govern: ing the construction of trusses and substantially the re. quired strength obtained in all vertical planes, as determined by such laws. By allowing the metal to flow inwardly the outer lateral surfaces of the carline re main flat and enhance the general appearance of the structure. In the form shown in Fig. 4, each extremity of the airline is provided with alongitudinally projecting lip 11'' and two laterally extending wings a o the lip a resting preferably in a'suitable recess formed on the top surface! of the side plate B of the car and the Wings a a being secured thereto by means of bolts 0 passing through holes in said wings and through said plate, as shown in Fig. (S.- In the simple form shown in Figs. 1. to 3, the lip 'a is omitted. The structure may be further modified by supplying the top of each wing a with a'projeeting lip a such lips also resting preferably in suitable recesses formed in the top surface of the side plate. The simple form shown inFig. 1 may be ordinarily used, as it has been found that under ordinary conditions the lips 11'' and a are unneces- Sttly.

Havingthus described my invention in detail, that which I particularly point out and distinctly claim is:

l. \s a new article of manufacture, a carline formed of :in integral piece of sheet metal and of inverted ll-shaped "L'i'ion. providwl wilh recesses in its top portion for receiving the rooflpurlinslhat portion of the metal of the side members of the rline intermediate of each of such depressions and the :u out lower cdge of the side members being of greater thickness than that of the main portion of such members.

2. \s a new article of manufacture, a cal-line oi. inverted U-sh-nped cross tion at the upper portion of each extremity and laterally extending wings adjacent to said projection, each wing provided at its upper portion with a lip or projection.

3;. As a new article of manufacture, a carline struck up from an integral piece of sheet metal and of inverted U- shuped cross (CllUli the side-members of the carline being perpendicular and the top portion 01' the cal-line being provided with recesses for the reception of the roof-purlins: the metal of such side members which is intermediate of the snidrecesses and the botlom of the carline bcing of a thickness greater than lhnt ol' the main portion of such side members; the outer surfaces of the latter forming the i extreme lateral planes oi the structure.

4. As a new article of manufacture, a carline struck up from an integral piece of sheet metal into a form having an inverted U-shaped cross-sectimn and havingat the upper portion of each extremity an extending lip or projection and laterally extending wings adjacent to said projection, each wing being provided at 1 upper portion with a lip or projection; the sidcmembers of the carline being perpendicular and the top portion of the carline being provided with recesses for the reception of the roofpurlin's, the .metal of such side-members which is intermediate of the said recesses and the' bottom of the carline being of a thickness greater .than that of the main portion of such side members and the outer surfaces of the latter forming, the extreme lateral planes of the structure.
